python 如何把文本中每行的色值，替换为随机值，

Question

我要把文本中每行的色值如#ffe1f1ff：，替换为随机值，

注意：文本中有一样的色值比如#ffffffff有两个，替换为随机值时不能一样

文本文件代码如下：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="Blue_1">#ffe1f1ff</color>
    <color name="Blue_10">#ff1853c2</color>
    <color name="abc_search_url_text_normal">#ff7fa87f</color>
    <color name="all_apps_label_text">#00000000</color>
    <color name="all_apps_label_text_dark">#61ffffff</color>
    <color name="all_apps_prediction_row_separator">#3c000000</color>
    <color name="all_apps_prediction_row_separator_dark">#3cffffff</color>
    <color name="tooltip_background_dark">#e6616161</color>
    <color name="tooltip_background_light">#e6ffffff</color>
    <color name="transparent">#00000000</color>
    <color name="uninstall_bg_color">#80000000</color>
    <color name="uninstall_split_line_color">#12ffffff</color>
    <color name="uninstall_target_hover_tint">#e6616161</color>
    <color name="volume_settings_icon_color">#7fffffff</color>
    <color name="white">#ffffffff</color>
</resources>

import re
import random

filename = "01.xml"
with open(filename,'r',encoding='utf-8') as f:
    xml = f.read()

def fp(p):
    return "#ff{:0>6x}".format(random.randint(0x0,0xffffff))
xml = re.sub(r'#[0-9A-Fa-f]{8}',fp,xml)
print(xml)

with open(filename,'w',encoding='utf-8') as f:
    f.write(xml)
